The object of the present invention is to provide a kind of heating device for lithium ion power battery, when the battery temperature of lithium-ion-power cell was lower than normal working temperature, this device can heat lithium-ion-power cell, and guaranteed homogeneous heating, efficiency of heating surface height.
For achieving the above object, the present invention has adopted following technical scheme: a kind of heating device for lithium ion power battery, comprise the lithium ion battery body, the heating collar that the periphery parcel of described lithium ion battery body is made by heating film, battery management system BMS monitors the temperature of lithium ion battery body in real time, and outputing control signals to temperature controller, temperature controller heats or stops heating to heating collar after receiving this control signal.
As shown from the above technical solution, the present invention superscribes the heating collar with heating function by the periphery at the lithium ion battery body, can make lithium ion battery in its battery temperature is lower than the normal working temperature scope, promptly under the situation that vehicle can't start, about ten minutes, be heated to normal operating temperature range, thereby can make normal vehicle operation, the present invention is to battery body or to single battery cell parcel heating material, guarantee homogeneous heating, safe in utilization, the efficient of insulation and heating is higher.
Description of drawings
Fig. 1 is a circuit diagram of the present invention;
Fig. 2 is the partial circuit figure between temperature controller among the present invention, the heating collar.
Embodiment
A kind of heating device for lithium ion power battery, comprise the lithium ion battery body, the heating collar 2 that the periphery parcel of described lithium ion battery body is made by heating film, battery management system BMS (Battery Management System) 3 is the temperature of monitoring lithium ion battery body in real time, and output control signals to temperature controller 4, temperature controller 4 heats or stops heating to heating collar 2 after receiving this control signal, as shown in Figure 1.
In conjunction with Fig. 1, described heating collar 2 is a resistance type heater, and its thickness is 1mm, and heating collar 2 is set on the lithium ion battery body, and the shape of the lithium ion battery body that its shape and its are wrapped up matches.The heating film of making heating collar 2 adopts that multiple high temperature resistant organic material, macromolecular material, carbon element and high-temperature fibre are compound makes novel thermo electric material, but is the planar heat producing body of an instead of part metal heating wire as heater element.Compare with the metal electric heating silk, heating film have softness, folding, corrosion-resistant, heating is fast, heating is even, energy-conservation, insulation, advantage such as ventilative, can be applicable to heating, insulation and the drying of all kinds of devices.
In conjunction with Fig. 1, described lithium ion battery body is single battery or a plurality of battery cell 1, and heating collar 2 is set in respectively on single battery or a plurality of battery cell 1.The present invention uses the heating film of one millimeter thickness to make heating collar 2, and the shape of heating collar 2 is decided according to the demand of different battery profile materials, capacity and concrete spatial placement, and single battery is directly wrapped up, and 1 of a plurality of battery cell are wrapped up respectively.The battery cell 1 of each lithium ion of the above high capacity lithium ion battery of 20AH is joined a heating collar 2 separately, the power of heating collar 2 is bigger, power is decided according to battery number capacity cascade system, power supply is taken from lithium-ion-power cell, the power demand of a common electronic passenger car heating collar 2 of high speed wing-rooms on either side of a one-story house compact lithium ion is not less than 2KW, can guarantee that battery rises to the normal working temperature scope from low temperature about 10 minutes, thereby normally start vehicle.
In conjunction with Fig. 1,2, described battery management system BMS3 is by CAN bus and temperature controller 4 communications, temperature controller 4 links to each other with the power supply high-pressure side of heating collar 2, the power supply low-pressure end of heating collar 2 respectively, the positive pole of the power supply high pressure termination lithium ion battery body of heating collar 2, the negative pole of the power supply low pressure termination lithium ion battery body of heating collar 2.The base stage of the output termination triode Q1 of described temperature controller 4, the grounded emitter of triode Q1, the collector electrode of triode Q1 connects the input of optocoupler U, optocoupler U connects the 5V direct current, the parallel circuits that the output connecting resistance R of optocoupler U and field effect transistor Q2 form, the drain electrode of field effect transistor Q2 connects the power supply high-pressure side of heating collar 2, and the source electrode of field effect transistor Q2 connects the power supply low-pressure end of heating collar 2.Because heating collar 2 is resistance-type heating elements, under the situation that has a plurality of battery cells 1, the heating power of each independent heating collar 2 is subjected to the resistance value of single heating collar 2 and the carrying voltage control of single heating collar 2, the operating voltage of each heating collar 2 is AC/DC 3V~220V, in order to guarantee that heating collar 2 is operated in the safe voltage, heating collar 2 adopts earlier, and series connection back mode in parallel links to each other with the both positive and negative polarity of lithium battery, as shown in Figure 1, be to connect with 2 series connection of two heating collars and then mode in parallel, the number of concrete series connection is decided on the battery cell 1 of different capacity.
